IDE :: Animated Mask Over Top Of Colored Rectangle
Sep 10, 2009
I'm attempting a neat little effect where I've got a fellow walking (already drawn and animated) and I'm using him as a mask over the top of a simple colored rectangle - the idea being, by changing the color of the rectangle, I can have a walking man with color effects happening. At this stage the square is just green, because the mask is not quite working correctly. The edges of the animated mask glitch up and don't work as expected

Am I completely hallucinating or what ? That's several years I'm working with Flash, and today, i want to do the simplest animation ever, and it just doesn't work....I want to mask an animated clip with an animated mask (a shape animation), but every time the mask arrives at a keyframe, the clip restarts to the frame 1 !!I added a piece of code to see at which keyframe it is blocked, and at every mask keyframe, the code says 'TypeError: Error #1009: null property..

I have a button that when clicked is supposed to draw a rectangle behind my mask layer but when I try to run it I get this error:
1067: Implicit coercion of a value of type Class to an unrelated type flash.display:BitmapData.
Here is the related ActionScript Code:
fabric_mc.phoenixFab.addEvenetListener(MouseEvent.CLICK, changeFabric);
function changeFabric(event:MouseEvent):void{
this.graphics.beginBitmapFill(phoenixFabric);
this.graphics.drawRect(181, 46, 319, 319);
this.graphics.endFill
}

Being a complete beginner in AS3 (and coding in general), I'm trying to do the opposite of what's seen in this swf (I'd like to have the spinning logo filled with the background colors): [URL]. I was thinking of a very simple way with this kind of code:
ActionScript Code:
var i:int=0;
var logo_vector:MovieClip=new LOGO_VECTOR();
logo_vector.x=192;
logo_vector.y=140;
//logo_vector.cacheAsBitmap=true;
[Code] .....
But while a logo_vector.rotation makes the logo spin around the Z axis and works, the rotationX gives a black screen. AS I could see the logo appearing onone frame, I thought that caching as bimtap on each frame would do the trick but it doesn't. I tried to put the logo into another movieclip but still no chance.
I thought about drawing the logo into a new bitmap as well, and then do a work on the pixels directly to have an opaqe background and the black logo transparent but there again, I can't get the logo position to refresh properly (and can't get it to be in the center of the bitmap).
I tried to copy the sprite into a bitmap:
var masque:BitmapData=new BitmapData(384, 282,true,0x00ffffff);
var masque_bmp:Bitmap=new Bitmap(masque);
and
Masque.draw (logo_vector);
In the Enter Frame function but I'm getting an empty rectangle and if not used as mask, the graphics are not refreshed)?

I have a curved graphic that I need masked, but the mask will slowly unveil the graphic below. I'm tweening the mask on the timeline since the graphic has a pretty complex shape (a bunch of curveTo's would take forever).If I apply a shape tween to the mask it doesn't tween on curves that well unless I place a keyframe at every two frames and adjust the shape. Does anyone know if there is a better solution?

I've got this interactive storybook that loads each page from separate swf files into a movie clip. The movie clip is masked, and with every turn of the page, the mask changes shape so it looks like the pages are covering up the content. Once the page turn is complete, we're supposed to be left with two fresh pages so we can load more content.
Here's my dilemma: It seems the movieclip unloads itself when the mask enters a new keyframe. I don't know how to work around this. I've tried making a separate movie clip out of the mask, and animating it on its own timeline, but that hasn't worked. Nothing else reacts this way to a moving mask. [URL]

I want to create a mask from an animated line. I found out pretty quick that you can't use a line to mask, only fills. So, can I convert the line to a fill as it's being drawn? Or do I need to put multiple instances of a shape along my line at intervals?
I keep seeing requests for an animation of writing. I figured it would be easier to have the text in one layer and use the animated line as the mask. It sounded good in theory.
I've attached my test that shows the line being drawn. I was playing around with some different objects to use as masks and that's how I saw that lines can't be used as masks. I wish they could.

I've got a movieclip with two layers - a background movieclip, and above that, a mask movieclip (as you might guess, this layer is masking the first). Due to design necessity, the mask is animated on the timeline across 60 frames.The problem arises when I use an Event.RESIZE listener to change the width of the parent movieclip when the browser window is resized. Any code to reference the mask, i.e
parentMC.contentMask.width = stage.stageWidth;
parentMC.contentMask.x = frame.width/2 - frame.contentMask.width/2;
Simply results in the mask animation not playing at all.

I have a site that is fairly complex, but was using a massive amount of CPU power, even when sitting idle on a page with no animations. I went through everything with a fine toothed comb, and couldn't find the culprit.So I just started removing layers one by one, until I found the one causing the problem.
Turns out it was a layer with an animated mask. I have a large black recatangle, that I converted to a mask, and then used a shape tween on it. Once that was triggered. The CPU usage went up 65-75%. Even when the movie was stopped on a frame that that mask didn't exist on. Once it was triggered, the rest of the time you are on the site the CPU usage is through the roof. I can do to fix that. Is there some other way I should build an animated mask?

For those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you.So I needed to get a Scrollbar, which I got hereThe thing is, it works with Sprites.After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have.
So I tried adding the TextFieldExtended instance to a Sprite instance using addchild.A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it.My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible?

I am trying to convert a rectangle(actually multiple rectangles) to a curved rectangle. I think it should be pretty easy but I guess i am stupid. Basically I would have a start position and stop position (many of these), and they would be converted to curved rectangles and follow in a cicrle around.

I would like to create a rectangle inside of a rectangle, starting approximately 15% inward from the right side of the other rectangle.
I know how to create rectangles with:
Code:
var newHotRect:MovieClip = new MovieClip();
newHotRect.graphics.beginFill(0x00FF00);
newHotRect.graphics.drawRect(0, 0, 100, 100);
addChild(newHotRect);
But how would I make another rectangle on top of that (the black one pictured) that is approximately 15% from the right?
I toyed around with .right, and .bottomright with no success. Can anyone lead me in the right direction? or even finding the x and y of the upper right or bottom right side of a rectangle?

how to respond when a rectangle hits another rectangle? I already know how to detect the collision, I just don't know how to respond to it. I'm just trying making a simple side-scrolling platform game where I have platforms I can walk on and bump against on all sides. I have searched everywhere and just can't find the tutorials I'm looking for.

I have been tyring to export an animated banner, in animated.gif format. it's a simple animated text with no gradients. it should go on top of a graphic which has some gradients and is multi-coloured and with effects (the colours are similar to the one/i used in the page) as you can see here the text looks a bit funny.url...

Is there a color transform tool that lets me affect the brightness of colored pixels only? For example, if I have an image that has a lot of grays and blacks, but a colored dot in the center, is it possible to only affect the brightness of the colored portion?
The solution I'm looking for does not involve making the colored dot in the center its own movie clip, just so you know.
